Hi all,
i hope someone can help me with this. I have been googling for days now, but
cannot find a solution.
I have set up a Ubuntu-10.10 that boots from a iSCSI disk using iscsistart in
the initrd.
What is the version of open-iscsi being used? What is the kernel version?
Is this some iscsi boot functionality built into ubuntu or something you
have put together?
When are you starting iscsid? Is it from the initramfs/initrd or from
the init scripts right after we have switched from the initramfs/initrd
to the real root disk?
This works fine so far!
But in order to secure the connection against target reboots, i tried to start
iscsid.
Unfortunately this does not work, iscsid stops the connection and then fails to
start it again:
root@localhost [~] # iscsid -f -d8
iscsid: cannot make a connection to 134.102.176.37:3260 (-1,2)
We cannot seem to connect to the portal's address. That is the correct
ip and port, right? When iscsid is run, is the network up? Can you ping
the initiator nic at this time?
It seems that the network should be up because iscsistart logged in, but
I think when you switch from the initramfs/initrd to the real root disk
maybe iptables could screw things up or of the normal nic setup stuff is
run it could screw up the network (if maybe the initramfs and normal
init network stuff is not in sync it could mess things up).
Any ideas?
What do
"login failed STATE_XPT_WAIT/R_STAGE_SESSION_REOPEN 0"
and
It is just internal state info. xpt wait means we were waiting to
connect to the target and session reopen means we were trying to reopen
the session. 0 means it was the first try.
"Cannot match (null) to net/scsi interface."
mean?
It means we did not have any iface info. If you were not binding the
session to a specific offload card or nic then this should be null. The
default is to not bind.
